Symbiosis in Friendship

Lately a friend has been sharing some discoveries of really neat examples of unusual animal friendships, and it got me thinking ...

Examples like this really remind me that even when someone is categorically different from you (introvert vs extrovert, boisterous vs reserved, assertive vs shy, mushy vs non-demonstrative, etc) you can enjoy an equally awesome relationship just as much as if they were categorically similar.

These differences in style and personality traits should be celebrated and  appreciated because of the balancing effect -- both people bring something  valuable to the table ... what one lacks the other is good at, what's hard for  one is easy for the other, and visa-versa. So they help one another as a perfect  team.  SYMBIOSIS!
